Additional Details

The P74FCT157CTP is housed in a 16-pin DIP (Dual In-line Package). It operates from a single 5V power supply. The device features four independent 2-input multiplexers, each with its own select input. The common enable input allows for disabling all outputs simultaneously. It's suitable for a wide range of digital logic applications where high speed, low power, and reliable performance are essential. This device is commonly used in computer systems, communication equipment, and industrial control systems. The propagation delay of 4.7ns ensures fast data selection, minimizing delays in critical signal paths. The P74FCT157CTP is a reliable and cost-effective solution for data selection and routing needs.
